GENERATOR FOR HYDROCARBON-BURN ERS.

SPECIFICATION forming part cf Letters Patent No. 666,785, dated January29, 1901.

Application filed June 5, 1899. Serial No. 719,491. (No model.)

2b all wiz/0m it may concern:

Be it known 'that I, JOHN F. WILLIAMS, a citizen of the United States,residing at Kansas City, in the county of Jackson and State of Missouri,have invented certain new and useful Improvements in Generators forHydrocarbon-Burners, of which the following is a specification.

My present invention pertains to improvements in generators forhydrocarbon-burners, lhe construction and advantages of which will behereinafter set forth, reference being had to the accompanyingdrawings,wherein- Figure l is a longitudinal sectional View of thevaporizing tube or chamber; Fig. 2, a similar view of aslightly-modified form; Fig. 3, a transverse sectional View on the linel l of Fig. l, and Fig. 4 a plan view of the wiregauze which is employedin the construction illustrated in Fig. 2.

The object of my invention is to so construct the vaporizing-tube of ahyd rocarbon-burner that although the hydrocarbon is fed directly to theinner surface or face thereof, yet the sudden explosions which usuallytake place are entirely prevented.

The construction also provides an unobstructed passage from the, tipback to the source of supply of hydrocarbon,wherebyfull pressure of theliquid hydrocarbon is permitted to act directly against the vapor in thebore of the generating tube or chamber.

The present construction also serves the useful function of providing ameans which allows the tube to be readily cleaned out when occasionrequires.

The vaporizing-tube herein shown and described is designed to be used inthat type of vapor-burners wherein the vaporizing tube or chamber passesover the burner or in such close proximity thereto that the heat issuingfrom the burner Will vaporize the hydrocarbon passing into and throughthe vaporizingtube.

Referring to the drawings, A represents the vaporizing tube orchamber,which in the form shown comprises simplya section of pipe havinga cylindrical bore. Upon the outerend of said pipe A there is mounted atip B, provided with a restricted outlet C, through which the vaporizedhydrocarbon or gas passes.

In the form shown in Fig. l it will be noted that said tip upon itsouter end is provided with a countersunk depression D, which facilitatesthe cleaning out of said opening C should the same become clogged,before the lamp is put in operation, by any foreign matter passing intosaid opening along with the vapor or gas. Mounted within said vaporizingtube or chamber is a cylinder E, formed of wire-gauze, the outer face ofsaid cylinder lying next to and in direct contact with the inner wall ofthe vaporizing chamber or tube. As will be seen most clearly uponreference to Fig. l, said cylinder has a free and unrestricted passageextending through the length thereof, and in actual construction of lthedevice I have made said gauze cylinder to extend throughout the lengthof the vaporizing-chamber, or nearly so. Said gauze cylinder may bereadily formed by taking a piece of wire-gauze of the proper length andwidth and rolling it up upon a wire, so that the external diameter ofthe cylinder will be approximately equal to the interior diameter of thevaporizing tube or chamber and make a close fit therewith. In y the formshown in Figs. l and 3 the interior bore of said gauze cylinder is ofthe same diameter throughout, whereas in Fig. 2 I have shown aconstruction wherein the interior bore of the cylinder decreases towardthe discharge end of the vaporizing-chamber. This latter construction ofthe cylinder may be readily formed up out of a piece of gauze cut to theshape shown in Fig. 4.

The operation of the device is as follows: As the liquid hydrocarbonflows into the vaporizing tube or chamber it naturally follows the gauzeand is carried around thereby to the entire surface of the vaporizingtube or chamber. The liquid hydrocarbon is thus presented in the mostextended manner possible, and as the particles of the hydrocarbon liquidare transformed into vapor the sudden explosions which take place areentirely checked by reason of the gauze.

It has been found by actual test that a vaporizing-chamber constructedin the manner herein set forth will give better results than one whichis plain throughout, the gauze tending, as just stated, to absorb theshock of the explosion or to hold the newly-formed vapor IOO in placeand permit it to pass out through the opening G in a steady stream andnot in a series of puffs or spurt-s.

Aside from serving to distribute the oil and regulate the iiow of thegenerated vapor or gas the cylinder also serves as a means 'ofcollecting foreign particles which pass into the chamber along with theoil, and by unscrewing said chamber from its support or removing the tipB therefrom said cylinder may be Withdrawn and cleansed when occasionrequires. It maybe unrolled, cleaned, and rerolled and again inserted,or it may be cleaned without the necessity of unrolling it.

From the construction shown in Fig. 2 it will be seen that therestricted passage or bore ofathe cylinder serves as an additional meansAfor preventing the generated gas or vapor from passing out of the tipin puffs, since the gas would naturally force its Way backward ratherthan through the restricted opening toward the dischargeoutlet. Saidform is Yeqn ally as well adapted to be wi thd rawn from the generatingtube or chamber and cleansed.

The amount of pressure exerted against the minute opening in the tipdepends entirely on the construction of the apparatus employed. By usingair-pressure on top of the liquid in the reservoir any desired pressurecan be obtained, and by using gravity only the pressure will always bethe same and depends entirely on the height of the reservoir above thegenerating-tube.

The important feature of this invention is the use of the cylindricalWire-gauze to eliminate the explosions and furnish an unobstructedpassage from the reservoir to the tip.

Having thus described my invention, what I claim is- 1. A generatingtube or chamber for hydrocarbon-bu rners, comprising an outer chamberand a filling of gauze placed therein against its inner wall, saidfilling having an opening extending longitudinally therethrough,substantially as described.

2. In a hydrocarbon-burner, the combination of a generating tube orchamber; and a filling of wire-gauze mounted therein against the innerwall thereof, and having an open space or chamber extendinglongitudinally therethrough.

3. In a hydrocarbon-burner, the combination of a Vaporizing tube orchamber; a cylinder of wire gauze mounted therein and adapted to comeinto close contact with the inner wall of the tube, substantially as andfor the purpose described. l

4. In a hydrocarbon-burner, the combination of a generating tube orchamber; a cylinder of wire-gauze mounted therein and adapted to comeinto close contact with the inner wall thereof, said cylinder beingremovable, substantially as and for the purpose described.

5. In a hydrocarbon-burner, the combination of a generating tube orchamber; a cylinder of wire gauze mounted therein and adapted to comeinto close contact with .the inner Wall thereof, said cylinder having adecreasing interior area toward the discharge end of the tube.

In Witness whereof I hereunto set my hand in the presence of twowitnesses.

JOHN F. WILLIAMS.
